Hi,
I hope that folks can give me some simple approaches to taking the data set
below, which is accumulated in two columns called "long" and "group", then
arrange the data is the "long" column into a data frame containing five
variables: "Group 1", "Group 2", "Group 3", "Group 4", and "Group 5". I am
hoping for a few different techniques which I can pass on to my students.
Thanks
